01 - Press tofu for at least 10 minutes to remove excess water, then cut into 3/4-inch cubes.
02 - Whisk together soy sauce, lime juice, maple syrup, chili flakes, garlic powder, and lime zest in a bowl.
03 - Add tofu cubes to the marinade and let sit for at least 15 minutes, gently tossing to coat evenly.
04 - Combine cornstarch, panko breadcrumbs, salt, and black pepper in a shallow dish.
05 - Remove tofu from marinade, reserving excess liquid. Toss each cube in coating mixture until well covered.

07 - Drizzle reserved marinade over tofu during the last minute of frying for enhanced flavor.
08 - Transfer crispy tofu to a plate lined with paper towels. Serve immediately garnished with chopped cilantro, chili slices, and lime wedges.
