Kozák started his career in 2001 with Czech club Slezský FC Opava, first playing with its youth teams before being promoted to the first team in 2007. Considered a promising talent, Kozák was a prolific goalscorer in the Czech Second Division with Opava. In October 2007 he scored his first hat-trick, coming in a 5–1 Opava win against FC Zenit Čáslav in the second division.
In January 2008, Kozák went on trial with English Premier League club Portsmouth, however he did not join Pompey. At the end of the season, Italian giants Lazio came calling and Kozák accepted a move to Rome.
After a season at Lazio, the club loaned him to Serie B side Brescia for the 2009–10 season, to gain experience and regular playing time. On 26 September 2009, Kozák scored his first goal in Italy against Grosseto.
At the end of his loan spell, he returned to Lazio. He scored his first goal for the Biancocelesti on 18 September 2010, scoring the winner against Fiorentina. He went on to score the winner against Sampdoria on 16 January 2011. Two weeks later he registered his third and fourth goals for Lazio, against Fiorentina once again. He later won the attraction of Michal Bílek, manager of Czech Republic, as the latter made a special trip to Stadio Olimpico to watch his game against Bari.
In the 2012–13 season Kozák, under coach Vladimir Petković, had a two faced season where he failed to score in 19 appearances in Serie A, but finished the season as the leading goal scorer in the Europa League with 8 goals. He scored his first club hat trick vs VFB Stuttgart in Rome on Thursday 14 March 2013, helping his team reach the last eight by an aggregate score of 5–1.
On 2 September 2013, Kozák signed a four-year deal with English side Aston Villa for €6.5 million transfer fee, being assigned the number 27 shirt. On 14 September 2013, Kozák made his Aston Villa debut at Villa Park, but couldn't prevent the side from losing 2–1 to Newcastle United. On 21 September 2013, Kozák scored his first goal for Villa, seconds after replacing Christian Benteke, against Norwich City which proved to be the winning goal in a 1–0 victory. On 9 November 2013, Kozak scored his second Villa goal with a header in a 2–0 victory against Cardiff City. On 4 December 2013, he scored the second goal in a 3–2 victory over Southampton.
Kozák received his first call up for the senior Czech national team on 15 March 2011, when coach Michal Bílek selected him in his squad to take on Spain and Liechtenstein, however Kozák did not make his senior international debut.
