Drain the tofu and wrap it in a clean kitchen towel or paper towels, placing a heavy pan on top to press out excess moisture for 20 minutes.
Preheat your oven to 400 degrees Fahrenheit and line a baking sheet with parchment paper.
Cut the pressed tofu into even slices about half an inch thick.
In a shallow bowl, whisk together the olive oil, lemon juice, garlic powder, oregano, salt, and pepper.
In a separate small bowl, combine the nutritional yeast and hemp hearts.
Dip each tofu slice into the lemon-herb liquid, then dredge in the nutritional yeast mixture until evenly coated.
Place the tofu slices on the prepared baking sheet in a single layer.
Bake for 25 to 30 minutes, flipping halfway through, until the edges are golden and the crust is crisp.
Serve immediately as a high-protein main or slice into strips to top salads and grain bowls.
