Dice the zucchini and saute in a small splash of oil over medium-high heat until golden and cooked through. Season with salt and pepper.
Combine the flour, sugar, salt and baking powder in a bowl and whisk well. In a separate bowl, whisk together the eggs, oil and milk.
Pour the wet ingredients into the dry and mix until just combined. Add the zucchini, corn, cheese and herbs and fold in.
Heat approximately 1cm of oil in a pan set over medium heat.
Add spoonfuls of the batter and allow to cook for 1-2 minutes per side until golden brown and crisp.
Remove and allow to drain on paper towels. Serve with lemon slices.

Notes
You can also grate zucchini on the large holes of a box grater but I prefer the texture of diced zucchini. If using shredded zucchini, I would still suggest sautéing to get rid of as much liquid as possible. Alternatively, squeeze the moisture out in a kitchen towel.
