Chris Carpenter is easily the comeback player of the year in the NL after pitching just five games and winning none over the last two seasons. He will have more competition for the Cy Young award, but he would get my top vote. He led the NL in ERA at 2.24, and his 17-4 record led to the best winning percentage as well. One knock against Carpenter is that he didn't pitch 30 games and finished with less than 200 innings pitched. However, for a guy coming off of a major injury, I think he was pretty resiliant. When he was pitching, he was the best in the NL, and I think he put in enough time to earn the award.
