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.

Kozák joined Lazio in July 2008, signing a five-year contract, with rumours that Lazio club president Claudio Lotito paid a €1.2 million ($1.8 million) transfer fee. He later went on loan to Serie B side Brescia in the 2009–10 Serie B 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, Kozák returned to Lazio and scored his first goal for the Biancocelesti on 18 September 2010, which turned out to be the winner against Fiorentina. On 16 January 2011, he netted the deciding goal against Sampdoria after coming on as a 77th-minute substitute, before scoring two goals on his full club debut two weeks later, again against Fiorentina. Having achieved four goals in nine starts for Lazio of which four goals came in January, Michal Bílek, manager of the Czech Republic, called Kozák up to the national team and announced he would make a special trip to the Stadio Olimpico to watch his game against A.S. Bari. Under coach Vladimir Petković in the 2012–13 Serie A, Kozák experienced a two-faced season by failing to score in 19 appearances in Serie A, but finished the season as the leading goalscorer in the Europa League with eight goals. He scored his first club hat-trick against VfB Stuttgart in Rome on 14 March 2013, helping his team reach the last eight by an aggregate score of 5–1.

On 14 September 2013, he made his Aston Villa debut at Villa Park, but could not prevent the side from losing 2–1 to Newcastle United. On 21 September 2013, he 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. The same year on 21 December 2013, he scored the only goal for Villa in a 2–1 loss to Stoke City at the Britannia Stadium. On 2 January 2014, Villa announced that Kozak had broken his right leg in a training ground collision with teammate Ciaran Clark, and would miss the rest of the 2013–14 season. Complications and further injuries saw him miss the entire 2014–15 season too. He eventually made his comeback 15 months after the initial leg break in March 2015 in an under-21 match against Wolverhampton Wanderers. He made his first team comeback in July 2015 in a 3–1 pre-season defeat to Fulham, scoring for the first time since December 2013. In February 2017, with Kozak's contract running out at the end of season, Aston Villa announced that he would miss the rest of the season undergoing surgery on his ankle.
