Hi,
Im not sure that I fully understand what you are trying to achieve, but this may help:
You can re-use the same item view that was submitted (either put it on a new form or reuse the same form and just hide certain controls based on parameters), and from there just execute a read method to get the data from your smartobject based on the item ID and you can build a link to that form and put it in your email. You can use parameters/references from the workflow designers context tab to get things like your current item ID.

Please feel free to share more information on what your process is so we can assist you much better
