I would start with a couple of simple selfies just to show any changes that have happened over the intervening years, such as change of hair style. Also make sure the stats are still accurate. That at least will make it easier for anyone responding to a casting call.
In termsof what to add well that will inevitably depend on the market you are aiming for now. The rule with portrait photography is show what you want to sell. I would say it is no different for modelling. If you want want to shoot glamour then make sure you have those images up. If you are more interested in doing art nude then go for that first.
