Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Pat the extra firm tofu very dry with a clean kitchen towel and cut it into 1/2-inch uniform cubes.
In a large mixing bowl, combine the tofu cubes, rinsed chickpeas, and broccoli florets.
Drizzle with olive oil and sprinkle with sea salt, black pepper, garlic powder, and smoked paprika, tossing until every piece is evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25 minutes, flipping halfway through, until the tofu is golden and the broccoli is tender.
While the vegetables roast, whisk together the nutritional yeast, lemon juice, and tahini in a small bowl, adding a teaspoon of water at a time until it reaches a smooth, pourable consistency.
Place the fresh spinach in a wide serving bowl and top with the hot roasted tofu, chickpeas, and broccoli.
Garnish the bowl with hemp seeds and pumpkin seeds, then finish by drizzling the zesty nutritional yeast sauce over the top before serving.
