How to stop 3 year old from door kicking?

My soon to be 3 year old keeps kicking his bedroom door at naptime and bedtime. I've tried everything to make him stop but he keeps doing it. We now have a huge hole in his door that im going to have to replace when we move out of our rental in a few months. Ive tried a babygate but he gets out, putting him firmly back in bed everytime he gets out, telling him in a stern voice "no kicking", taking away bed buddies (made kicking worse), ignoring him, smacked his butt and yelling. Im at my whitts end with him! Any suggestions would be greatly appreciated.
