I would say to go with 3000 cals. and 150 g. carbs, with 2g. per lbs. bodyweight protein, the rest of fat. Healthy fats of course. Up the carbs by 40-50g. per week if you feel like you can have more. This will give you minimal weight gain, and maximum mass. It worked for me, so I guess its pretty good. Eat 7 meals a day, and keep track of your progress.
