or:

- select and copy
- yank (it's called yank in emacs, not paste).
- select and kill the text you wanted to substitute

Use delete-region-and-yank instead of yank:

(defun delete-region-and-yank (&optional arg)
  "Deletes region if mark is active and yanks the last kill.
Always replaces the region with the yank, whether the region was
selected via keyboard or mouse.  Also works for normal
yank even with ARGS (thus it can be mapped to \\C-y)"
  (interactive "*P")                    ; raw, like yank.
  (message "arg=%S" arg)
  (cond
    (mark-active                        ; delete region
     (let ((str (buffer-substring (point) (mark))))
       (delete-region (point) (mark))
       (if (string=* str (current-kill 0 1))
           (let ((str2 (current-kill 1 1)))
             (kill-new str2 t))))
     (if arg
         (yank arg)
         (yank)))
    ;; else no region selected:
    ((consp arg)                        ; delete forward sexp
     (set-mark (point))
     (forward-sexp 1)
     (delete-region-and-yank))
    (arg (yank arg))
    (t   (yank))))
