This might not count, but Rian Johnson said that the overheard shot of Kylo Ren and the stormtroopers waking into the Rebel base on Crait was inspired by the overhead shot of Anakin and the clones marching into the Jedi Temple in Revenge of the Sith.

There are also some musical callbacks to the prequels. In TFA, the track “Finn’s Confession” is reminiscent to “Talk of Podracing” from TPM.

In TLJ, the track “Old Friends”, which plays as Luke and Rey are entering the cave with the Prime Jedi mural, plays a variation of the mystery motif from Attack of the Clones. You can hear this motif in the “Mystery of the Clones” track from AOTC, for example.

For a more straightforward callback, there is a battle droid in Babu Frik’s droid shop in TROS.
