Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Remove the tofu from its packaging and press firmly between clean kitchen towels or paper towels for 5-10 minutes to remove excess moisture.
Cut the pressed tofu into 1/2-inch cubes and chop the red bell pepper into bite-sized pieces.
In a large mixing bowl, combine the tofu cubes, chickpeas, broccoli florets, and chopped bell pepper.
Drizzle with olive oil and sprinkle with sea salt, black pepper, garlic powder, and smoked paprika, tossing well to ensure everything is evenly coated.
Spread the mixture in a single layer on the prepared baking sheet, ensuring the tofu isn't overcrowded so it can crisp up properly.
Roast for 25 to 30 minutes, tossing the ingredients halfway through, until the tofu is golden-brown and the vegetables are tender.
Remove from the oven and immediately sprinkle the nutritional yeast and hemp seeds over the hot mixture, tossing gently to coat.
Drizzle with fresh lemon juice and serve warm in a large bowl.
