I'm not much taller than you, similar lifts, if your body composition is anything like mine, we aren't blessed with easily putting weight on. We have to make an extra effort, but take advantage of it, losing it on the other side comes easier, too.
I don't track calories (I suspect you don't) but I know what 800-1000calories looks like in a meal and I'll get 5 of them in a day. Not suggesting you have to do the same (I "do my cardio" so will burn a dose), but at least get a rough guide.
