The Mandalorian is a brilliant show and did a great job integrating itself in the Star Wars universe and the fans liked how the story went back to the basics and gave us all of the things we loved about the trilogy, and it did that without starring any characters from those original movies.
It managed to pull that off with a story and natural tone, but there were also a ton of other Star Wars Easter eggs in the TV series including the droids, planets, and species seen in the movies.
ScreenCrush has made this video that breaks down all of these references, and how they relate to the saga. This should help you over until The Mandalorian Season 2 released next month!
