Data Repeating Characters into Muliple Columns

I have tens of thousands of rows of data that come in like the following:
This+is+a+test
The problem is I have to break this down and put it all together in multiple ways. Everything before the first Plus needs to remain intact and keep the +, but all remaining pluses need to be changed to "-". Then I need to have everything in between the "-" broken into columns of which those individual elements need to be edited using another list using vlookup, edited and then concentated back into one column with the delimiters.

Its a little more complicated because some have multiple +'s, some have just one and some have +'s and -'s. I have attached a sample. I've made some progress but need everything from column E and on sorted so I can do the vlookup on them.

Oh and everything using vlookup needs to be changed to something else. Some are already correct and output to the same thing.
