The pancakes and muffins are all fine straight from the freezer (thawed obviously - I mean you dont' need to re-heat).
At this age they can eat just about anything. The only things to watch out for a whole nuts (choke hazard) and honey (until 12 months), sugar, salt. They can eat chunks of meat, bread sticks, crackers, anything with out without teeth (I buy a range of various crackers and put them in a big tin for DS to choose from, he loves getting the choice, esp now he is a little older). Gums are very hard and can gum through anything, it even helps with teething pain. My LO has been chomping on all sorts since 6 months, no purees.
For more veg, you could just steam some sticks and pop them in a tub to eat cold the following day, or roasted/baked wedges. Raw veg are also good if your LO will take them. Mine wasn't over keen at that age but many are, grated carrot for example.
There are several recipes for the oaty chews on one of those links, various flavours combos, once you've tried it a couple of times you can experiment. They freeze great too. I think the recipe will be near the end of one of the threads, and initially called something like dairy free, gluten free sugar free oat cookies.
