I have changed the values of dotspacemacs-smartparens-strict-mode and dotspacemacs-smart-closing-parenthesis from the default nil to t in my .spacemacs file. As far as I can remember, that's the only paredit-ish customisations I have done. And by the way, I use smartparens everywhere, not just in Lisp modes.

Generally, the Spacemacs defaults work really well for me, and for many others. Elisp hacking was more relevant in the past. These days, with Spacemacs and other similar community efforts that deliver sane and well thought out settings, not much tinkering is required.
