In a separate bowl, whisk together the syrup, yogurt, pumpkin, milk, eggs, and vanilla.
Add the wet ingredients to the dry and gently mix just until incorporated. Lumpy batter makes fluffy pancakes, so DO NOT over-mix.
To make the topping, just whisk together the yogurt, vanilla bean paste, nutmeg, and orange zest. Serve over warm pumpkin pancakes!
