I agree with Choco - you need more protein merely to preserve muscle on a calorific deficit.
To fool your body that you're not in calorific deficit and gain muscle you need to cycle calories in over calories out. Don't be in deficit more than 2 or 3 days a week, and vary the deficit. Eat a high carb, high protein meal followin strength-training workouts, with some dairy if you can tolerate it.
Check out the LeanGains protocol.
