Go to AdminCP, scroll down to smilies, select upload smilie. Choose the smilie you desire, give it a title, enter the text code it will use ex: ._. , select a display order, then click on Upload.

It'll automatically show up in your reply box. If you don't see anything, go to your UserCP and select options, scroll down to Message Editor Interface, then select Enhanced Interface.

If you upload a lot of smilies and want to show all of them in the reply box, go to adminCP, then select vBulletin Options, scroll down to Message Posting Interface Options, then change the value of how many smilies you want.

Hope that's basic.
