Preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper.
In a large bowl, whisk together flour, plant-based milk, cornstarch, garlic powder, onion powder, smoked paprika, salt, and pepper until you have a smooth batter.
Dip each cauliflower floret into the batter, allowing the excess to drip off.
Coat the battered cauliflower in breadcrumbs, ensuring they are well covered. Place them on the prepared baking sheet in a single layer.
Bake in the preheated oven for 20-25 minutes, flipping halfway through, until golden and crispy.
In a small bowl, mix the sweet chili sauce, soy sauce, and sesame oil to create a glaze.
Once the cauliflower is out of the oven, toss the crispy wings in the sweet chili glaze until fully coated.
Return to the baking sheet and bake for an additional 5-10 minutes for the glaze to caramelize slightly.
Remove from the oven and let cool for a couple of minutes before garnishing with chopped cilantro.
