Born in Dublin, Mooney joined Shamrock Rovers, his first senior club, in 2000, while he was a pupil in Coláiste Éanna, in Dublin.  and scored in every round when Rovers' won the U17 All Ireland title against Kingdom Boys in 2002. He made his first team debut coming on as a sub against Longford Town on 6 April 2004. His first goal came on 24 June 2004 against the doomed Dublin City. In his fifteen months in the first team he scored nine goals in 40 total appearances.
Due to Rovers' financial position at the time players had to be sold on and Mooney moved to Longford. His last game in the Hoops was against Cork City on 22 July 2005.
He made his Longford debut on 6 August 2005 in a 1–0 win over Bohemians. His scoring return of 19 goals in the 2007 League of Ireland Premier Division season ensured he was top scorer in the league . Mooney's goals also led Longford Town to the final of the FAI Cup. However despite Mooney's heroics throughout the season Longford Town were relegated to the League of Ireland First Division, albeit with a six-point deduction, and lost the FAI Cup final to Cork City.
His excellent form throughout the season did not go un-noticed and he was nominated for the PFAI Player of the Year and won the FAI Player of the Year  as well as the Player of the Month award for August 2007.
After Mooney's spectacular form throughout the 2007 League of Ireland season it was obvious that he would be playing somewhere else than First Division football in Flancare Park. He had been linked with a move to the Football League next season with Football League Championship sides Crystal Palace and Colchester United reportedly interested in signing the striker. Representatives from Premier League side Fulham were said to have been in attendance at the FAI Cup final, and Leeds United manager Dennis Wise had also watched Mooney in action.
However, Mooney promised to follow his manager Alan Mathews down south if he was to stay in Ireland. He had been offered a contract by English Premiership side Blackburn Rovers, but instead signed a longer three-year contract with perennial title challengers Cork City in January 2008 thus ending two and a half years in the midlands.
Mooney was a revelation in his only season with Cork City, racing to the top of the goalscoring charts again. He was widely regarded as one of the best players in the league. A particularly impressive showing against Derry City at The Brandywell saw Mooney score twice in a minute to bring the game (which Derry had dominated) level at 2–2, and come close to completing his hat-trick just moments later with a speculative 30-yard effort that came back off an upright (a spectacular goal from Denis Behan eventually gave Cork all three points). Before European football came to Turner's Cross midway through the season, Mooney had scored 18 goals in total, and broken his team mate Behan's record for a scoring run by netting 11 goals in six matches. He then scored on his European debut, in a 2–2 UEFA Cup draw with Finnish side FC Haka .
However, Mooney would only last another month at Cork City. It was revealed on 12 August 2008 that the club was in debt to the region of €800,000. However, this was not the only reason. Mooney's season was similar to Roy O'Donovan's the season before. Already top of the goalscoring charts, Mooney had attracted renewed interest from England. One of the clubs was Reading. On 20 August, he signed for them for a fee believed to be in the region of €260,000. Mooney was given squad number 12.
Loan to Norwich City
Mooney had a loan spell (cut short by injury) with League One side Stockport County midway through the 2008–09 season, but in March 2009, he moved on a month's loan to Championship strugglers Norwich City. He scored twice in his first three appearances for the Canaries, including the opener in a 2–0 win over Cardiff City and the only goal of the game against fellow relegation candidates Plymouth Argyle. As a result, Mooney's loan spell at Carrow Road was extended until the end of the season. Although he would eventually total three goals in nine league games for the club, his contribution would not be enough to prevent Norwich from being relegated.
Due to the different time-frame of the League of Ireland season, the end of the 2008–09 campaign brought Mooney his first break from playing and training since March 2008.
On 16 October 2009 it was announced that Mooney would be joining League One side Charlton Athletic on an emergency loan until 1 December. He made his first team debut the next day, coming on as a late substitute in Charlton's 2–1 victory against Huddersfield Town at The Valley. After two more appearances as a substitute, Mooney was handed his first league start for the club against MK Dons at The Valley on 14 November, and scored an equalising goal in the 13th minute to set the Addicks on their way to a 5–1 victory over their promotion rivals. He opened his side's account again in a 4–2 home win over Bristol Rovers on 24 November, prompting Charlton manager Phil Parkinson to extend Mooney's loan deal with the club for another four weeks, until 28 December.
Having played a part in three of his side's goals, Mooney sustained a knee injury in the club's 4–4 draw against arch-rivals Millwall on 19 December, which saw him out of action for the rest of 2009. He returned to Reading at the end of the year, only to re-join Charlton again on 14 January in a new loan deal set to run until 11 February. However, on 28 January, Mooney's loan was extended until the end of the season.
Mooney finished with six goals from a total of 31 appearances for the Addicks, with one goal coming on his last appearance for the club, a League One play-off semi-final defeat (Charlton had won 2–1 on the night, but lost the tie after a penalty shoot-out) against Swindon Town.
Loan to Colchester United
On 5 August 2010 it was announced that Mooney would be joining League One side Colchester United on loan until 3 January 2011. He came on as a substitute in the U's first league game of the season, a 2–2 draw at Exeter City. Mooney then scored twice on his full debut for the club, with a pair of first half goals in a 3–0 League Cup win over Hereford United. He scored his first league goal for Colchester in a 1–1 draw at home to Carlisle United on 27 August.
Mooney initially had a loan deal which ran until 6 January, but decided to return to Colchester United for the remainder of 2010/2011 season. He finished as the club's top scorer with 14 goals in all competitions as they finished in 10th place in League One. With his Reading contract expiring in June 2011, Mooney became a free agent. However, in July 2011, it was reported, after some speculation, that Mooney would not be returning to the U's on a permanent basis.
On 23 July 2011, Mooney signed his first permanent contract since 2008, a two-year deal with League One side Leyton Orient, where he linked up with former Norwich City team-mate Jamie Cureton. He scored his first goal for the club in a League Cup game against Bristol Rovers, following it with a goal against Blackburn Rovers in the next round. Mooney then scored his first two league goals, away at Yeovil Town on 25 October, as the game ended 2–2.
Mooney would go on to tally 21 goals in his first two years at the club. On 21 June 2013, it was announced that Mooney had signed a new two-year contract with Leyton Orient, with manager Russell Slade hailing him as intrinsic to the way that Leyton Orient play. He started the 2013–14 season with aplomb, scoring 8 goals in the first 10 games of the League One season.
