As a starting point you may use this (untested code):

(defun format/align-and-newline ()
   (interactive)
   (let* ((start (progn (beginning-of-line) (point)))
          (end   (progn (end-of-line) (point)))
          (line (buffer-substring start end))
          (words (split-string line)))
      (delete-region start end)
      (insert (first words))
      (dolist (word (cdr words))
         (insert (format "%*s%s" 6 "" word))) ; you want something else here.
      (insert "\n")))

(local-set-key (kbd "RET") (function format/align-and-newline))
