Ok for starters, you need to figure in the venting of the room and the oder control all at the same time. If you do not have a light already you may want to check out Cool Tubes. They cool very easily therefore needing less fan. If you are ok as far as opening the closet doors can you leave them cracked and have a fan blowing up at the light? There is a small carbon filter called the Elf or the Goblin made for closets and tents. First thing, do a test run with just the light in the room and record some temp and humidity numbers. That should give you some ideas on how much of what you need. Just read journals, can't read enough on this site.
Peace,
