CMcAboy, this is actually a very common background for people coming into bschool with an interest in management consulting - and believe it or not, you seem to have done a pretty good job already of articulating the goals! Basically what you need to do is to show how you're ready for the stated future path, and the sketch you provided above gives us some insights that you have transferable skills and an understanding of what the job entails.
The beauty of having a consulting goal is that not much else needs to be said about the goal itself - it's not like if you want to be an entrepreneur, where you need to bring in so much specific detail and backup. The adcoms totally know what management consulting is about, they send a gazillion graduates into that field each year, you don't have to explain or describe anything about that post-MBA goal specifically. Instead, you want to add enough color to your goals essay to show that it's a "real" goal for you - not just one that you heard about somewhere and you think it sounds good. Layer in the research you've done, talk about the reasons you want to do it, and/or give a lot of details surrounding what you want to do and how you plan to get there. And no matter what, you'll want to include some 'proof' that you're qualified, based on high-powered stories and concrete examples from your background that shows your readiness.
The goals essays are never easy and we haven't even touched the L/T goal which is a whole other issue, but we wanted to reassure you that it sounds like you're totally on the right track! It's much harder to transition from a straight IT/tech role into consulting but not impossible; the fact that you've already made a transition to consulting in your field will add a lot of value. Now, it just comes down to how you pitch it on the page. The basics look like they're there.
