auto-mode-alist can be used to associate a certain type of file with a
major mode.  Every major mode has a hook variable that can be used to
customize that major mode.  In this case you can do

(add-hook 'paragraph-indent-text-mode-hook (lambda () (auto-fill-mode 1)))

to automatically start the auto-fill minor mode whenever you start the
paragraph-indent-text major mode.  If you want auto-fill-mode started
only for .plan files and not for other files that are put in
paragraph-indent-text-mode, then you could start auto-fill-mode
conditionally (e.g., write a function to do this and put this function
on paragraph-indent-text-mode-hook).
