Are you sure you want a touring bike? A touring specific bike is great for loaded touring but they are heavier and generally slower than a road bike. I don't think (not sure) any touring bikes are made women specific but many do have smaller sizes.
Trek and Specialized (and others) make several women specific models of road bikes. A Specialized Sequioa is a road bike not a touring bike but you could put a rear rack on one along with many other road bikes. You may want to look at something like the Specialized Dolce.
