Efficient Vegan Carbs and Fats

I feel like I have protein figured out but constantly have to work to get enough carbs and fats in my diet without exceeding the number of calories I'm shooting for. I had some good advice to tweak my protein intake down a bit, and this helps free up calories for other macros but it's still a challenge. My target macros are in line with what most online calculators and a previous fitness coach recommended. Do you have any great hacks for calorie efficient carbs and fats on a vegan diet?
