I have also embraced evil. In my experience, token shortcuts work after
you enter insert mode, toggle them off and then on again. They then work
fine until you restart proof general. I bound a key combo to be able to
toggle unicode tokens:

(global-set-key [(control f12)] 'unicode-tokens-mode)

So, open a .thy file, enter insert mode, hit ctrl-F12 ctrl-F12, type
\lambda and you get λ. Same for --> , \forall etc.

Here are some other helpful settings to act more vim-like, and an
example how to do something like :nmap Y y$

(require 'evil)
(evil-mode 1)

(define-key evil-motion-state-map (kbd "<down>") 'evil-next-line)
(define-key evil-motion-state-map (kbd "<up>") 'evil-previous-line)
(define-key evil-motion-state-map (kbd "<left>") 'evil-backward-char)
(define-key evil-motion-state-map (kbd "<right>") 'evil-forward-char)
(define-key evil-normal-state-map (kbd "<insert>") 'evil-insert)
(define-key evil-insert-state-map (kbd "<insert>") 'evil-replace-state)
(define-key evil-replace-state-map (kbd "<insert>") 'evil-insert-state)
(define-key evil-normal-state-map (kbd "<delete>") 'evil-delete-char)

(evil-define-operator evil-yank-line-end (beg end type register)
  "Yank to end of line."
  :motion evil-end-of-line
  (interactive "<R><x>")
  (evil-yank beg end type register))

(define-key evil-normal-state-map "Y" 'evil-yank-line-end)

I hope this helps.
