I looked high and low (read: I did a cursory search) and couldn't find a recipe for oatmeal waffles that was vegan but not gluten free. As someone who likes to deal with one major dietary restriction at a time, I adapted my own based on this recipe from Taste of Home.

These are dense, filling waffles with just a touch of sweetness. I highly recommend eating them drizzled in the strongest ginger syrup you can make.
Makes about 8 waffles on my waffle iron, but your milage may vary.
- 2 tbsp ground flax seeds
- 1 1/2 cup all purpose flour
- 1 cup rolled oats
- 3 tsp baking powder
- 1 tsp ground cinnamon
- 1/2 tsp ground nutmeg
- 1/4 tsp salt
- 1 1/2 cups almond milk
- 6 tbsp vegan butter, melted
- 2 tbsp brown sugar
In a small mixing bowl, whisk the ground flax with 5 tbsp water (that's equivalent to 1/4 cup + 1 tbsp of water). Let this sit for at least five minutes.
In the mean time, combine the flour, oats, spices, and salt in a medium mixing bowl.
Whisk the milk, butter, and sugar into the flax mixture.
Stir the wet ingredients into the dry until just combined.
Allow the batter to rest while your waffle iron pre-heats, then cook the waffles according to your iron's instructions.
 Ginger syrup is made by bringing a 1:1 solution of sugar and water to a boil, and then simmer with peeled and chopped ginger for ~35 minutes. The end result is gingery simple syrup and delicious candied ginger. There's a proper recipe for this on Daring Gourmet.
