Congratulations on your success!
A lot of trial-and-error comes into play on the maintenance stage, I found. I usually give myself some sort of buffer. I choose five pounds either way (losing too much/gaining too much). That range provides a little wiggle-room so you're not constantly stuck in the "diet" mindset and can eat on your terms -- which sound wonderful.
Otherwise, I found options are adjusting the food, adjusting the exercise or adjusting the mindset.
Food: I did find nutrition bars or a serving of almonds are a great "calorie buffer" when I'm just needing pure calories. I think of them like my vitamins in the morning. Something nutrient dense that can be easily removed as you so wish.
Exercise: ditch a day of exercise until you're at the range you want. Alternately, find a different routine to learn. Usually what I do; I know my calorie-burning exercises and my strength/stability/flexibility exercises, and I mix and match all those depending on my and my body's needs.
Mindset: Why'd you lose weight? Was a higher goal at mind? How many other ways can that goal be met you haven't tried yet? Were there things you were reluctant to do/try pre-weight loss? One big thing I learned is by focusing on expanding life in the same way I shrank my body, all the mechanics of diet/exercise/weight loss sort of fade into the background ... they don't require the Intense Focus they used to. Largely because I"m going after the kind of life I imagined post-weight.
You rock, congratulations and welcome! Onward!
