Preheat the oven to 180C/350F/Gas 4. Grease and line a 9x5-inch loaf pan with parchment paper. Set aside.
Whisk together the flour, oats, sugar, baking powder, baking soda, salt, and spices. Set aside.
Mix together the eggs, vanilla, vegetable oil, yogurt, and mashed banana. Add to the dry ingredients, and mix until just combined.
Pour the batter into the prepared pan and spread out evenly.
Bake for 50 - 60 minutes, or until a toothpick inserted into the centre comes out clean. If desired, cover loosely with aluminium foil halfway through baking to prevent browning too much.
Leave to cool completely in the pan on a wire rack before slicing and serving.
