Preheat your oven to 350°F (175°C).
Grease a standard 9x5-inch loaf pan with coconut oil or line it with parchment paper.
In a medium bowl, whisk together the flour, baking powder, and salt.
In a large mixing bowl, combine Greek yogurt, sugar, and eggs. Add lemon zest and vanilla extract. Mix until smooth.
Slowly drizzle in melted coconut oil while whisking the wet ingredients.
Gradually add the dry ingredients to the wet mixture, stirring gently until just combined.
Pour the batter into the prepared loaf pan and smooth the top.
Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the loaf to cool in the pan for 10 minutes before transferring it to a cooling rack.
In a medium bowl, whisk together powdered sugar and lemon juice to create the glaze.
Drizzle the lemon glaze over the cooled loaf.
