The book ‘The New Diary’ by Tristine Rainer has a variety of tools and methods for precisely this expansion of journaling (which go much beyond prompts, so if you’re looking narrowly for just prompts then it may be the wrong level of abstraction), and claims that these tools and methods in fact constitute a basis set for the activity.
(FWIW, the book was updated multiple years after its publication, and the author claims that she hasn’t found anything not covered by the intervening years not covered by the basis.)
