Preheat oven to 400 degrees Fahrenheit (204 degrees Celsius).
Line a large rimmed baking sheet with parchment paper.
Pat the cubed tofu and chickpeas dry with a clean kitchen towel to ensure crispness.
In a large mixing bowl, combine the tofu, chickpeas, broccoli, bell pepper, zucchini, and red onion.
Drizzle olive oil over the mixture and toss to coat evenly.
Sprinkle nutritional yeast, garlic powder, smoked paprika, salt, and pepper over the ingredients and toss again until well distributed.
Spread the mixture in a single layer on the prepared baking sheet.
Roast for 25 minutes, tossing halfway through, until the vegetables are tender and the tofu is slightly golden.
Remove from oven and serve immediately.
