(defun my-format-theorem-blocks ()
  "Format theorem blocks in org."
  (interactive)
  (save-excursion
    (goto-char (point-min))
    (while (re-search-forward "#\\+begin_theorem" nil t)
      (let ((beg0 (match-beginning 0))
	    (beg (1+ (match-end 0)))
	    (end0 (save-excursion
		    (re-search-forward "#\\+end_theorem" nil t)))
	    (end (match-beginning 0))
	    content c)
	(setq content (split-string (buffer-substring beg end) "\n" t))
	(delete-region beg0 end0)
	(insert "Theorem :\n")
	(while (setq c (pop content))
	  (insert (format " | %s\n" c)))
	(insert " +----\n")))))

M-x my-format-theorem-blocks RET

But this in a one-way only... no return.

HTH,
