Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
In a mixing bowl, whisk together the flour, water, garlic powder, onion powder, smoked paprika, salt, and pepper to create a batter.
Dip each cauliflower floret into the batter, ensuring even coverage, then roll in breadcrumbs to coat thoroughly.
Arrange the coated cauliflower on the prepared baking sheet in a single layer. Bake for 25-30 minutes, turning halfway through, until golden and crispy.
In a separate bowl, toss the baked cauliflower with buffalo sauce until well coated. Return to the oven for an additional 5 minutes to set the sauce.
While the cauliflower is baking, warm the corn tortillas on a skillet for about 30 seconds on each side until pliable.
To assemble the tacos, place a generous amount of buffalo cauliflower on each tortilla.
Top with sliced avocado, shredded red cabbage, and a sprinkle of fresh cilantro.
Serve with lime wedges on the side for added freshness and zest.
