Preheat the oven to 400°F and line a large baking sheet with parchment paper.
Press the tofu with a heavy object for 10 minutes to remove moisture, then cut into half-inch cubes.
In a large mixing bowl, combine the tofu, chickpeas, broccoli, and cauliflower.
Drizzle with olive oil and sprinkle with sea salt, garlic powder, smoked paprika, and black pepper, tossing until evenly coated.
Spread the vegetables and tofu in a single layer on the prepared baking sheet.
Roast for 25 minutes, flipping halfway through, until the tofu is golden and the broccoli edges are crispy.
While the tray is in the oven, place the kale in a bowl with lemon juice and massage with your hands until the leaves are dark green and tender.
Remove the tray from the oven and immediately sprinkle with nutritional yeast, tossing to incorporate the savory flavor.
Divide the massaged kale into bowls, top with the roasted vegetable mixture, and garnish with hemp seeds and pumpkin seeds.
