After completing his secondary education at St Mirin's Academy in Paisley, Hay signed for Celtic in 1966. He became one of the "Quality Street Kids" reserve team which eventually took the places of the ageing Lisbon Lions. He made his league debut on 6 March 1968 against Aberdeen going on to make 230 appearances for Celtic scoring 12 goals, winning 5 League Championships, 3 Scottish Cups and 1 League Cup. After playing for Scotland in the 1974 World Cup in West Germany, he was transferred to Chelsea following a dispute with Celtic. In 1979 a serious knee injury forced him to retire from the game as a player. He had also suffered problems with a detached retina and eventually lost full vision in his right eye. He won a total 27 caps for Scotland.
His first venture into football management was when he took over the reins at Motherwell in 1981 following Ally MacLeod. He led Well to the Scottish First Division title and promotion to the Scottish Premier Division. He left at the end of the 1981-82 season.
Hay then succeeded Billy McNeill as Celtic manager in 1983 winning the Scottish Cup in 1985 and the Scottish Premier League in dramatic fashion in 1986. Celtic won their final game 5–0 against St Mirren at Love Street but needed Hearts, who were league leaders and favourites to lift the trophy, to lose to Dundee at Dens Park. Albert Kidd secured the victory for Dundee with two goals and Celtic were crowned surprise champions. Hay made way for Billy McNeill to return to the Celtic managership in 1987.
In 1991, Hay took on Paisley club St. Mirren but left a year later.
Hay then teamed up with Jim Leishman in 2000 to join ambitious club Livingston and led the club to the Scottish First Division at the end of season 2000-01 and the club's first promotion to the Scottish Premier League. Their debut season in 2001-02 saw an impressive season which earned them their first qualification into Europe with a UEFA Cup place. The 2002-03 season wasn't as impressive and they both stepped down from the management position although they both stayed at the club. Brazilian Marcio Maximo Barcellos took over.
He then returned to the manager's job shortly into 2003-04 season, this time in full charge taking over from Marcio Maximo Barcellos after just 9 games of the season. Hay then went on to win the Scottish League Cup while the club was in administration, beating heavy favourites Hibernian (who beat Celtic and Rangers on route to the final). Despite this success, the veteran boss was released at the end of the season to be replaced by Allan Preston, one of his first team coaches, by new chairman, Pearse Flynn of the Lionheart Consortium.
Hay was then appointed manager of Dunfermline Athletic, succeeding Jimmy Calderwood. He rejoined with Jim Leishman who was the Fife club's Director of Football. Unfortunately he proved one of the least popular managers in the club's history, and was sacked near the end of the season with the club struggling in the Scottish Premier League.
