I may be missing something but could you not simply use

  [[vref:fig:log-expt-7]]

(along with description text if you wished) and define an org link as
below?

#+begin_src elisp
  (org-add-link-type "vref" nil
                     (lambda (path desc format)
                       (cond
                        ((eq format 'latex)
                         (format "\\vref{%s}" path)))))
#+end_src

(untested)
