Preheat your oven to 220°C (430°F) and line a baking sheet with parchment paper or a silicone mat.
Drain the tofu and press it firmly to squeeze out excess moisture, then cut it into bite-sized cubes about 2 cm (0.8 inches) wide.
In a small bowl, whisk together the cornstarch, garlic powder, smoked paprika, and salt until well combined.
Place the tofu cubes in a mixing bowl, drizzle with soy sauce, and gently toss to coat evenly. Let sit for about 5 minutes to absorb the flavors.
Spritz the tofu lightly with neutral oil using a spray bottle or brush to help the coating crisp up during baking.
Add the coated tofu to the bowl with the cornstarch mixture, tossing gently until all pieces are evenly coated. Shake off any excess coating.
Arrange the tofu cubes in a single layer on the prepared baking sheet, making sure they aren’t touching for maximum crispness.
Spray or brush the tofu lightly with more oil, then sprinkle panko breadcrumbs over the top for extra crunch.
Bake for 25-30 minutes, flipping the tofu halfway through, until the edges are golden brown and the coating feels crackly when pressed.
Remove from the oven and let rest for 5 minutes, allowing the coating to set and crisp up further.
Serve the crispy tofu nuggets hot with your favorite dipping sauce or add them to bowls for a plant-based crunch.
