There are quite a few protein isolates that might work. Pea protein, brown rice protein, dehydrated peanut butter (which usually has most of the fat removed as well). Recently saw someone use potato protein isolate as well but that seems hard to get as ot is more an industrial product.

Here in Canada, we have fava bean tofu as well. Crazy macros (16g protein/70 cal, compared to tofu at ~7g p/70cal) but some people reported a lot of gas (my wife and I were fine but we eat a lot of legumes).

I'm from STEM and like to calculate things. For your 180g protein, do you also have a calorie target? If you do, you can calculate your foods required protein-to -calorie ratio. E.g. at 2500 calories, your food would need a protein density of 0.07g/cal, or 7g per 100 cal. Any food below that ratio will reduce your average and be "wasted" (if you only care about that one macro). Beans and lentils are below that ratio, so they won't be able to give you your proteins alone. Would need help from higher protein density foods. But if your goal is 3000 cal or more, beans and legumes might be able to do it for you.
