Tofu is a general go-to as a meat alternative because of the high amount of protein, the many ways it can be cooked, and for being able to take on flavors well. Basically it's very versatile. Lots of advice online for cooking tofu for a curry. My general advice is to freeze every block of tofu to give it good texture, then thaw and press. For a curry just think about if you want the tofu to be hard and firm, or more tender as this will impact how it is cooked.
