Tofu will soak up flavourful marinades like a sponge, particularly if you cut it into bite-sized pieces first.

Try a simple marinade of soy sauce and rice wine to begin with, and then start playing around with things like hot sauce, yuzu, minced ginger, garlic, and honey.

Let it marinate for at least 15 minutes, though the longer you can let the tofu marinate, the more flavourful it will be.
