My recommended kit list for one night and two days hiking would be:
Rucksack
Tent
Sleeping bag
Sleep mat
Waterproofs
Stove with fuel and fire steel to light it. If you're taking a Trangia, there is no need to carry all the pans as they are all extra weight.
Billy (if you're not taking the Trangia)
Cup if you really must have a hot drink, otherwise drink out of the bottle.
Spork
First aid kit (basic to control bleeding, maybe some pain killers but not much else unless you are trained to use it)
Map and compass and someone who knows how to use both
Water carrier (the lighter the better)
Toilet paper and a trowel for use in emergency
Food and water or water purification if there will be a reliable source of clean water.
Emergency rations to be used only in an emergency!!!
Small pocket knife. No need for a survival knife or survival tool or multi-tool as they are all extra weight.
In my very humble opinion (and from bitter experience) you are out there to enjoy the walk and the camping, not to lug around a load of kit you probably won't need.
When you get home, go through your kit and look at all the stuff you didn't use (except for the emergency kit). Take it out and don't take it next time.
Please let us know how you get on.
