What are some good easter eggs in LOZ OOT or LOZ MM

Not many come to mind, but if you look at the Happy Mask Salesman's bag in Majora's Mask, you'll see a Mario Mask on the back. Also, Adult Malon and Cremia wear a broach that looks like Bowser. OOOH! And in Ocarina of Time (The old one, not the 3DS one), if you look through the window on the right of the castelo Courtyard, there's pictures of Mario, Luigi, Bowser, Peach, and Yoshi. In the 3DS version, they're replaced por a setup of an area as if it were in the original Mario Brothers.

There is one easter egg that is the stone leitura from Super Mario 64. If you want more, click the link.
