Preheat the oven to 400° F. Line a baking sheet with parchment.In a bowl, mix the cream cheese, green onions, garlic powder, and soy sauce. To assemble, spoon 1 rounded teaspoon of filling onto each wrapper. Brush water around the edges of the wrapper, then bring the corners of the wrapper together in the center and pinch to seal the cream cheese inside. Place on the prepared baking sheet. Brush each Rangoon with oil. Bake for 12-15 minutes, until crispy. If the Rangoons are browning on top, cover with foil. To make the sauce, combine all ingredients in a bowl. Serve topped with green onions and dip in chili sauce.
