You can use a calorie calculator to estimate your maintenance calories and add 200 - 500 on top.

Obviously these are not 100% accurate so you have to do some finding out for yourself. See if your weight changes at all after being on those calories for a week, if it does, stick to them, take the bulk slow, minimise fat gain, if you have not moved at all, slowly increase.

Aim for 1g of protein/1lbs of bodyweight and fill the rest up with carbs to fuel to workout, and fats to support hormones and overall bodily functions.

Fats are not your enemy, neither should they be over consumed. At least 60g of fat per day will keep you healthy.
