I would start with some good coconut milk or cream. Aroy-D is a brand that doesn't have any weird gums and such added.
If you do dairy you can also use milk, kefir, yoghurt, etc. as the base. Since you are trying to pack a lot of nutrition into a glass, you could even start with cream or sour cream.
From there mix in any fruit fresh or frozen, maca powder, and raw eggs. I'm not a big fan of protein powders either.
Also bone broths are very good for getting a lot of nutrition in a cup.
I hope you heal up well and soon.
