Pad - Neoair Xtherm long/wide and Exped pump bag with the valve modified to fit the Neoair. It also serves as waterproof liner. I'd still buy the same today, or maybe a XLite
Pillow - Trekology. Cheap pillow from Amazon.
Sleeping bag - MEC bag (today's equivalent is the Talon -3°C down bag) or Windhard quilt from Aliexpress (Enlightened Equipment clone). If I were buying today, I'd go with a 20°F down quilt from a small manufacturer like Enlightened Equipment, Zpacks, Hammock Gear, etc.
Tent - Tarptent Rainbow or a REI Quarter Dome UL 3. I bought those tents for solo and duo backpacking, otherwise I'd probably still use a Sierra Design Clip Flashlight. There's a slew of good tents for touring.

Sleeping bag, pillow and pad goes into a pannier with clothes. Depending on how many panniers I use (2 or 4), the tent goes on the rear rack or loose in a pannier with poles, rain gear, wet clothes and anything with an odd shape or food I don't want crushed, like a loaf of bread.
