So in my procedure call I have something like this
pro test, filename, var
restore, filename
plot, var
end
var will be the name of the variable I want to plot from restoring the
file. I'm thinking of giving var as a string in the procedure call. My
question is how would I do this and is it possible?

No problem, but use the solution from Lajos; using EXECUTE is bad
practice unless you have to (and I forgot about SCOPE_VARFECTCH).

Like this?
function mg_getsavvar, filename, varname
compile_opt strictarr
restore, filename=filename
result = execute('plot, ' + varname)
end

Look up SCOPE_VARFETCH in IDL help:
plot, scope_varfetch('my_var_name')
