In a large bowl, whisk together sugar, oil, eggs, grated lemon rind, lemon juice, and yogurt until smooth.

Sprinkle flour, salt, and baking powder over the wet mixture. Whisk gently until just combined; a few small lumps are acceptable.

Place the pan in the oven and immediately reduce the temperature to 350°F (180°C) standard or 320°F (160°C) fan/convection. Bake for 50 minutes or until a skewer inserted in the centre comes out clean.

Allow the cake to cool on a wire rack. Remove the sides of the springform pan, then remove the base once cooled. Dust with powdered sugar before serving.
