I was struggling and wanting the same thing since move from Vim to Emacs.
After some research and experimenting, I came up the function below which allow you to do the same thing with Evil package installed or using spacemacs.
It also works with region active (or visual selection in vim term) and that can be quite useful to replace word like abc-def-hij:
; replace current word or selection using vim style for evil mode
(selection (buffer-substring-no-properties (region-beginning) (region-end))))
(if (= (length selection) 0)
(message "empty string")
(evil-ex (concat "'<,'>s/" selection "/"))
(evil-ex (concat "%s/" (thing-at-point 'word) "/"))))
then in your init.el, define the same key binding:
(global-set-key (kbd "\C-co") 'evil-replace-word-selection)
keybinding is slightly different from vim one which is "space z" but I haven't figure out how to map that in emacs when evil mode is there. keep complaining not a prefix etc and I'm relatively new to emacs. But still not too bad and myself is happy with this solution at the moment.
