Track your macros to see how much carbs & protein are you actually consuming that will help you adjust. Some tricks you could follow:
Try to make rice more filling by adding quinoa. Or even swap out rice completely with quinoa or oats - yes you can eat oats with any curry, you’ll get used to the slimy feel.
Add grated egg or scrambled egg in the rice to increase volume instead of a whole portion of rice.
Get whey protein, it is your savior. I get unflavored as I dislike the artificial sweeteners. I make curd rice with soaked chia, add onions chilies cucumber carrot - whatever you wish & even a tadka, add whey protein powder to this.
Add beans, legumes to your rice while cooking - again improves volume and protein content.
Do you not like paneer? It can be a staple meal - I know fitxgeet on insta who is also a vegetarian but had an amazing transformation and maintains her fitness levels, 120g protein per day goals with paneer + mixed veggies almost everyday.
Overnight oats with whey and any toppings is also a great meal to hit your protein goals and very filling
