Flax seed should work. Here's how to substitute: https://www.thekitchn.com...

Another 1/2 mashed banana. I have also used applesauce in baking to sub for eggs, about 1/4 cup for 1 egg. If the applesauce is sweet, you may want to reduce the sugar in the recipe.
That's 1/2 mashed banana = 1 egg
I always use the 2-1-2 substitute. 2T water, 1 t oil, and 2t baking powder. Otherwise, you could substitute 1 T ground flax with 3T water per egg.

What recipe are you using? most of my quick breads recipes use two eggs.
Could you just halve the recipe?

Don't know your timing or your pantry, but two more possibilities:
* soft tofu (2 oz/quarter cup for each egg) buzzed up with the liquids in blender, processor or mixer.
* aqua faba (liquid from canned chick peas). See link for more details
