There's a "View your posts" button on the top banner - I don't know if that's what you're looking for. If you're meaning the vB/Huddler-style UserCP, that's not quite the same in phpBB. Go into your User Control Panel (same top banner) and select "Manage Subscriptions" - you'll have to subscribe to threads when you post to have them show up there. To do that, tick the "Notify me when a reply is posted" option in the "Full Editor" reply window (it only has to be done once per thread). Alternately when in a thread you want to sub to, click the "Subscribe to Topic" button on the bottom banner, underneath the "Who Is Online" segment (this saves you posting just to subscribe). 😀
