The upper headwaters area of the Deschutes from Crane Prairie up to Little Lava has shown off some really nice fish and on a variety of tactics. Small Streamers like a sculpin or leech style jig is a great producer, but don’t be shy about swimming them under logs and cut banks. A terrestrial like an ant or black beetle is super good on any forested river, and you are likely to see PMD and caddis hatches, possibly green drakes and golden stones too. I would not go to the Upper D w/o a clarks or norms, and also make sure to have a green drake sparkle dun and film critic too. 
This is super good water fo your Tenkara friends and is one of the ways I like to approach to the Upper Deschutes myself.
