Almond milk is about as high as you get in terms of protein (other than soy) if you can't have animal milks.
There's a decent cheese-substitute brand called Daiya that I'm pretty sure doesn't have soy (it's not soy-based anyway, it's arrowroot and tapioca IIRC). I don't know if it's high in protein, though; I'd guess not. [Edit: We have some in the fridge and I was right; it's only 1 g per serving.] I've never seen it anywhere but in health-food stores. All the grocery-store "fake cheese" brands I've seen are soy-based and usually use casein (a milk protein) to boot.
There are coconut-milk yogurts available now (even in regular grocery stores sometimes), though they're pricy, but again, I don't think that protein is especially high.
I'd suggest not even trying for 1:1 replacements for milk, cheese and yogurt and just get the needed protein from other sources.
