Add pancake mix and water to a large mixing bowl. Whisk until a smooth thick batter forms. Add strawberry pieces and fold into batter until evenly distributed.
Heat a skillet or griddle to medium high and coat with an even layer of cooking oil spray or vegan butter. Ladle approximately ⅓ cup portions of batter onto the cooking surface. Allow to cook for 3-4 minutes until bubbles appear on the surface of the pancakes and they begin to appear dry around the edges. Flip pancakes, cooking for an additional 4-5 minutes. Remove from heat and set aside.
To make the strawberry puree, add berries, water, and agave nectar in a blender and blend until smooth. Pour into a bowl and set aside. Top pancakes with dollops of vegan yogurt, drizzle with strawberry puree, and sprinkle with granola and strawberry pieces.
