Preheat the oven to 350F. Line an 8x5-inch loaf pan with parchment paper on bottom and 2 sides; this will make lifting the loaf out of the pan super easy!
In a large bowl, cream together the eggs, sugar, vanilla and butter. Whisk in the lemon juice and plain yogurt. In a separate bowl, combine the dry ingredients: flour, baking powder and salt. Whisk in the dry ingredients gradually, whisking well after each addition.
Place blueberries into a bowl and toss together with 2 tablespoons flour until well coated. Fold into the batter along with the lemon zest using a spatula. Transfer the batter into the prepare loaf pan and spread it evenly to edges.
Bake in the preheated oven for 50 to 60 minutes, or until the top is set. Check for readiness by inserting a toothpick into the center; it needs to come out clean. Remove the bread from pan with the help of the parchment paper and set onto wire rack to cool.
For the lemon glaze, simply whisk together the lemon juice with confectioner's sugar. Adjust sugar amount to your liking; for a thicker glaze, add more sugar. Drizzle over the loaf. Serve loaf warm, or let cool completely then wrap in plastic wrap.
