On the iPad, you use the equivalent of the Mac's File->Open from Server Repository...

In the document chooser, tap the cloud icon, then choose your server repository in the popup window (or set it up, if it doesn't appear). Your published document(s) should appear. Once you've opened it, OmniPlan will save a copy in your local storage, and you can open that the next time you need to work on the document.
