Eat at a surplus of 10-20% over your maintenance and eat... let's say your body weight (or lean body mass if you know it) in grams of protein and half that number grams of fat as minimums. Minimums - essentially make your calories whatever you like after that.
If you feel better with more/less carbs, eat more/less carbs. Really doesn't matter so long as you've met your fat/protein goals and are in a surplus. Don't have to eat at specific times either (a la PWO meals or specific macro intake on training days, etc), just lift, eat more in the way you prefer and enjoy
