You'll need to

• Subclass vB_Friendly_Url/vB_Friendly_Url_Paged
  Take a look at vB_Friendly_Url_Member in class_friendly_url.php to see how that works - it's pretty straightforward.
• Create a Plug-in for Hook Hook friendlyurl_resolve_class to load your class if necessary
• Create an appropriate rewrite rule
• Use fetch_seo_url(), verify_seo_url() in your PHP code when you constructing URLs
• Use {vb:link} in your templates
