Alright, here are some questions, that might help people zone in on what you are looking for...
1) How long have you been lifting?
2) What is your current height and weight?
3) Do you keep a food log or anything like that?
Generally, beginners who are overweight have the easiest time of losing fat and gaining muscle at the same time. So, the more trained you are and the leaner you are, the harder it is likely going to be to achieve your goal.
Some people will swear it is easy for them to do this... while other's will swear it can't be done at all.
Anyway, there are some routines on this site which are recommended for trying to lean out. You could just pick one of them. I think most fat loss workous use fairly short rest periods, but I may be mistaken, I haven't done any of them.
