In addition to H1N1's great advice, I'd say add in either pullups/chinups and dips into your routine. They'll build muscle and have the added benefit of keeping the fat off. I know it sounds like broscience, but bodyweight movements have you moving your own body and fat gain is counterproductive to that. So the body seems to try it's best to keep the fat off.
I've seen it work that way many times.
