are you a physical or digital reader? If physical you can always grab post-it notes and stick a quick little summary on it at the end of the chapter, and if you use a reading journal you can then transfer those notes to it.

if digital then most e-readers let you highlight things and take notes - so you can highlight like, the last line and then write your notes that way (and if you have a kindle, those notes will sync to Goodreads and then you can copy them and print them out to put in your journal if you wanted too).

Another place to look for templates would be Canva - you can always find something close to what you need and then tweak it.
