Preheat the oven to 450°F (230°C). Line a baking sheet with parchment paper.
In a mixing bowl, whisk together the flour, water, garlic powder, onion powder, smoked paprika, salt, and black pepper until smooth.
Dip each cauliflower floret into the batter, allowing the excess to drip off, then roll in breadcrumbs, pressing gently to adhere.
Place the coated florets on the prepared baking sheet in a single layer and spray lightly with cooking oil.
Bake the cauliflower in the preheated oven for about 25-30 minutes or until golden brown and crispy, flipping halfway through.
While the cauliflower is baking, heat the buffalo sauce in a small saucepan over medium heat. Once the cauliflower is done, toss it in the warm buffalo sauce until fully coated.
To assemble the tacos, warm the corn tortillas in a pan or microwave until pliable.
Place a generous amount of the buffalo cauliflower on each tortilla, then top with shredded lettuce, diced tomatoes, cilantro, and drizzle with vegan ranch dressing if desired.
Serve immediately and enjoy your delicious buffalo cauliflower tacos!
Notes
Vegan ranch dressing is optional but adds a nice touch.
