Preheat oven to 375 degrees F. Spray scone pan with cooking spray or grease with butter.
Combine the flour, baking powder, baking soda, salt, sugar, and orange zest in a large bowl. Set aside.
In a separate bowl, combine the egg, yogurt, melted butter, and orange juice. Add the wet mixture to the dry mixture all at once. Fold the wet ingredients in gently just until moistened. Lumps will remain and that is okay.
Spoon mixture evenly into each section. Bake for 20-25 minutes until golden brown on top. Allow to cool for 15 minutes before removing from pan.
Meanwhile, mix powdered sugar and orange juice for glaze in a small bowl until smooth. If needed add up to 1 additional orange juice to achieve a smooth pourable glaze. Use a spoon or fork to drizzle glaze over each scone.
