Maybe you should get away from the idea of meat substitutes and veggie versions of meat dishes and try actual born-as-veggie dishes, such as:
dahl and basmati rice,
chick pea curries and rice,
marinated tofu kebabs,
falafel and pitta breads,
bean and pasta soups,
pasta with pesto and peas,
pasta with broccoli and ricotta
spinach and mushroom pancakes,
mushrooms cooked with garlic, parsley and white wine, served with crispy toast (or blended to make a paté)
tabbouleh made with quinoa,
hummous with breadsticks and raw vegetables,
omelettes/tortillas/frittatas,
quinoa cooked with lemon and ginger, with peanut butter stirred in (fake satay/Thai flavour)
etc etc etc.
My DD was eating all these from 6 months (apart from the peanut butter bit, she got that at 9 months), so all are suitable for babies too. Just flavour the adult portions more after taking out the baby's portion. Most of these dishes are very easy (I'm not one for slaving over a hot stove) and freeze well, so you can even make batches.
If you stick to meat substitutes or eat style recipes you're going to be very limited and get bored quickly.
I'd recommend Sara Lewis' Veggie Food for Kids, it's also got a section with family meals in it and gives you a fair few ideas for experimenting yourself, as well as a wealth of nutritional information.
