Hummer, I have the same problem! Here's what I did before:

1. Eat every 3 hrs of high protein foods, or at least 6 meals/day. I also eat 1 hour before exercise and immediately within 30 minutes after exercise.

I also take protein shake (Mega Mass 4000), 1 serving a day.

2. Eat at least 1 gram of protein for every pound of your body weight (example: if body weight is 100lbs eat at least 100 grams of protein per meal).

3. Free weights exercises: i did dumbbell exercises Mon-Wed-Thurs. Taebo on Saturdays or sundays

My target weight gain: 1lb/week.
