In most cases no. In baked goods, eggs are an emulsifier, a binder and a leavener. They also have a role in preventing cakes from sinking in the middle (the higher the protein content of the cake, the less likely this is to happen).
Yoghurt is not a leavener; it is not possible to whisk in air bubbles until it's foamy in the same way that you can for an egg. (So this rules out genoise sponges, meringues, fatless sponges etc...)
Yoghurt is acidic, eggs are not. This extra bit of 'acid' in a recipe can through off chemical-based leavening reactions, resulting in some very peculiar tasting cakes. (Which rules out any baked good leavened by baking powder).
Yoghurt has a distinctive taste, which eggs do not have.
Eggs give baked goods a golden-yellow colour, which would be lacking if they were not used in the recipe.
Substituting an egg with another ingredient is actually very tricky, since eggs are pretty much unique in their properties. (Some people suggest using "blended up tofu", some people suggest using the gel from soaked flaxseeds as an alternative, but the results are invariably a bit weird compared to using eggs). If you need a recipe which does not use eggs, you'd be much better off finding a recipe which is designed not to need eggs, than trying to adapt a recipe which does.
A great substitute is soy yogurt.
Buttermilk.
you can substitute yeast with curd /plain yogurt
You can substitute yogurt for milk in a recipe by using an equal amount of yogurt as the amount of milk called for. This can help add creaminess and tanginess to the dish.
Sour cream.
They proposed to use yogurt as a substitute for meat in school lunches in 1996.
You can use Sour Cream of Mayonnaise as a substitute of yogurt.
A suitable substitute for curd in a recipe is plain yogurt.
Yes, you can substitute applesauce with yogurt in baking or cooking, but it may alter the flavor and texture of the dish. Yogurt adds creaminess and tang, while applesauce contributes sweetness and moisture. If you're using yogurt as a substitute, consider adjusting the sugar and liquid content in the recipe to maintain the desired consistency and taste.
Plain yogurt is usually a good substitute for mayo.
To substitute Greek yogurt for butter in a recipe, use an equal amount of Greek yogurt as the amount of butter called for. This can help reduce the fat content and add a tangy flavor to the dish.
You can use buttermilk or yogurt as a substitute for sour milk in the recipe.
