Commiserations on the injury — bad luck at any time, but particularly so on the eve of a climbing trip abroad.
I'm a little confused: you ask about walking in Lleida but go on to say you'll be on belay duty in Siurana and Margalef, both of which are situated in Tarragona province?
Either way, there's plenty to do. In Tarragona province a day or two walking on Montsant would provide you with some spectacular views, as well as giving you a tour of the various sectors — useful reference for your next trip. If your bad arm is up to a little moderate via-ferrata action you could take in the Grau dels Barrots and Grau del Carrasclet gullies (popular but adventurous routes) on your way to/from the summit plateau.
In Lleida, the aforementioned Montsec range is indeed stunning, and is laced with walking paths. Without knowing more of your plans it's difficult to be specific, but a few hours' stroll down into, and back out of, the incredible gorge of Montrebei would take you through some of the wildest scenery in Spain.
If you're staying near Siurana, the first thing I'd do would be to visit Tourist Information in Cornudella. I'm pretty sure they have a good selection of brochures and booklets dedicated to local walking routes.
Pete.
