It wasn't much different from Romney's. The first 25 minutes of Romney's 38 minute speech were dedicated to rhetoric about American dreams, American businesses, and American families, which included stories and comparisons about his own family, businesses, and how he can relate to most Americans. There were a few jabs about how Obama has done nothing for the country, but no specific details.
It wasn't until about minute 26 that Romney actually brought up some substantive facts about Obama's presidency by pointing out specific decisions that he thought were failures.
That lasts for a minute or so, at which point he starts talking about what he's going to do. But it's just more generalized statements about how he's going to create a brighter future, create more jobs, create financial security for seniors, etc. No actual plans on how he's going to do it (other than the vague statement, "I have a plan to create 12 million new jobs").
The only thing he mentioned that sounds like an actual plan was his reference to making use of resources in our own country (natural gas, coal, oil, etc.). Everything else was just a generalized, "I'm gonna do this!", but no specifics on how. We only get five minutes or so of these vague plans and promises before he goes back to criticizing Obama and talking about American ideals for the remainder of his speech.
I usually don't bother with listening to political speeches until the debates, and even then, they're still full of "plans" that will allegedly fulfill vague promises, and emotional rhetoric that gets the crowd chanting "U-S-A."
Welcome to politics.
