Exactly mate just build up slow. A good base will be obtained by going out for long slow runs/distance(LSD)this is the bread and butter of all distance runners. LSD is normally done once a week,this with a couple of shorter,more spirited runs will see minutes knocked of yout 10k time. As you just getting back into the swing of things i'd try just to run 3 times a week,if you can manage it around your lifestyle try not to put runs back to back,this will give you time to rest and/or stay away from injury.
