Place cream cheese in a large bowl and let sit at room temperature until softened.
Unwrap imitation crab and squeeze out the excess liquid, then shred the pieces into small bits. Finely grate or mince garlic cloves and thinly slice scallions.
Add soy sauce, granulated sugar, toasted sesame oil, garlic powder, and ground white pepper to the bowl with cream cheese. Mix until combined.
Fill a small bowl with water. Arrange wonton wrappers in a single layer, leaving a tiny space in between each. Dip a finger into the water and swipe it across the center of each wrapper.
Folding Option 1: Place 1 tablespoon of crab mixture onto the center of each wrapper stack, spread slightly, dampen edges, fold to form a triangle and pinch to seal.
Folding Option 2: Place 1 tablespoon of crab mixture in the center, dampen edges, lift corners up and pinch to seal, ensuring all edges are closed.
